What is this tool used for?
Size a portable power station from the running load, backup hours and usable battery capacity. Check both continuous output and the starting surge in the manufacturer's specifications.
How this is calculated
E = (P ÷ (η/100) + P₀) × t ÷ (D/100) ÷ 1000; Pₙ = P × (1 + m/100); P = Average AC load · W; η = Battery-to-AC efficiency · %; P₀ = Inverter idle draw · W; t = Backup duration · hours; D = Usable depth of discharge · %; m = Continuous headroom · %
Before you use the result
Size a portable power station from the running load, backup hours and usable battery capacity. Check both continuous output and the starting surge in the manufacturer's specifications.
